I keep going back and forth on this topic, this forum has a lot of vibrant activity so I was hoping for some input and counterpoints if its worth committing to Tandem now or playing the wait and see game through 2020.
- Current regimen: Medtronic 751 (530G) + Dexcom G6
- A1C’s : 7.0-7.5 over the past 18 months
- Pump is out of warranty
- Would consider DIY LoopDocs, but I have some reservations relying on a system that introduces new potential points of failure: 1) Old pump (722 & 723), 2) Riley Link, 3) code, 4) phone. I am inspired by what the Looping community has done here, but my preference would be to wait things out for Tidepool to succeed with the FDA and be released with a compatible ACE designated pump that is in warranty.
Omnipod is not an option as I need a 300 unit reservoir.
I’ve done all my research on Basal IQ & Control IQ. I’ve thoroughly researched its limitations and abilities. I still have some open questions I’m awaiting Tandem to answer and clarify as to how Control IQ behaves once the pump has exceeded 100 units delivered in a day, and how aggressive its basal adjustments are when it predicts a high or low; one of their product support sales reps told me last week that the system may ramp up to as high as 15 units an hour (15u/h also happens to be the pump’s max basal rate) but I have my doubts if Control IQ would manipulate basals so aggressively if it wil only issue bolus corrections at 60% of sensitivity and correction factors
I have reservations on acquiring T:Slim X2 now so late since it’s hardware debut and being locked into the platform once others and Tandem introduce updates.
I like the Medtronic reservoirs, AAA Battery, being able to Bolus by touch from my pocket discreetly in public or easily while driving if necessary. The Tandem hardware although it is more iPhone than Beeper concerns me: The screen getting cracked, having to charge the battery, concerns over eventual battery degradation
I have zero interest in 670G with what I consider its half baked Auto Mode + inferior Guardian 3 CGM system. I wouldn’t mind a future Medtronic pump if it worked with G6 but there does not seem a timeline for when Medtronic will have an ACE approved pump to work with Tidepool & Dexcom. I know Medtronic will share 780G trial results at the ATTD Conference in Spain in late February 2020; however that appears to be a pump with more aggressive algorithms + bluetooth, but still use the Guardian 3 sensors.
I’m tempted to commit to Tandem as soon as tomorrow for the simple reason of tying my CGM to my pump so as to increase % time by getting more aggressive on my basals and in-turn protect me from night-time hypos. Again, the consideration is what do we know coming in the near term, and is it worth waiting out the market?
Thank you for reading.
